Description

Technical Field

[0001] This invention relates to the field of slope protection block production technology, and in particular to a high-strength, lightweight, silt-based ecological slope protection block pressing and molding equipment. Background Technology

[0002] High-strength, lightweight, silt-based ecological slope protection blocks are a new type of slope protection material made primarily from silt through a special process. They combine high strength, lightweight, and ecological functions, aiming to solve the problems of high resource consumption and insufficient ecological properties of traditional slope protection materials, while realizing the resource utilization of silt.

[0003] High-strength, lightweight silt-based ecological slope protection block pressing and molding equipment is a specialized machine used to mix waste materials such as silt with specific additives and then produce slope protection blocks with high strength, lightweight properties, and ecological functions through a high-pressure pressing process. The structure of this equipment typically comprises five core modules: raw material processing, mixing and stirring, pressing and molding, demolding and output, and auxiliary systems. These modules work collaboratively to achieve efficient production. Existing block pressing and molding equipment often results in the mold and block being tightly bonded after molding, requiring manual tapping, increased demolding force, or extended demolding time for separation. This leads to prolonged molding cycles and reduced production efficiency.

[0004] To address the aforementioned issues, we propose a high-strength, lightweight silt-based ecological slope protection block pressing and molding equipment. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that after the blocks are formed, the mold and the blocks cannot be separated due to the tight adhesion, and separation can only be achieved by manual knocking, increasing the demolding force or extending the demolding time, which leads to a longer single molding cycle and reduced production efficiency. Therefore, this invention proposes a high-strength lightweight silt-based ecological slope protection block pressing and molding equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-strength, lightweight, silt-based ecological slope protection block pressing and molding equipment includes a frame, an upper mold inside the frame, connecting mechanisms at both ends of the upper mold, the upper mold being mounted on the frame via the connecting mechanisms, an opening at the lower end of the upper mold, a lower template at the bottom port of the upper mold, and a mold cavity formed between the lower template and the upper mold.

[0008] The frame is equipped with a demolding mechanism, which is connected to the lower template and assists in separating the lower template from the upper mold. The inner wall of the upper mold is coated with Teflon, and the upper mold is equipped with an injection mechanism, which is connected to the mold cavity and used to add raw materials into the mold cavity.

[0009] Preferably, the injection mechanism includes a feed pipe, the lower end of which is fixedly installed on the upper mold and communicates with the mold cavity. The upper end of the feed pipe is provided with two openings, one of which is vertically arranged and the other is inclined.

[0010] Preferably, a block is fixedly installed inside the feed pipe, a pusher block is slidably arranged inside the feed pipe, an exhaust port is provided on the pusher block, a screw is rotatably installed on the pusher block, the upper end of the screw passes through the block and is threadedly connected to the block, and a handle is fixedly installed on the upper end of the screw.

[0011] Preferably, the connecting mechanism includes a slide rail on the frame, a movable seat slidably disposed in the slide rail, a connecting block inserted into one end of the movable seat, the connecting block being horizontally movable, one end of the connecting block being fixedly mounted on the upper mold, two spaced-apart limiting holes being provided on the frame, and a limiting rod being provided on the frame, the limiting rod passing through the limiting holes and inserted into the movable seat.

[0012] Preferably, the demolding mechanism includes two symmetrically distributed strip seats, which are disposed within the frame and located below the lower template. Each strip seat has a slot, and the two slots are symmetrically distributed. A base is disposed within the frame, and the two ends of the base are respectively inserted into the slots on both sides. The base can slide within the slots. Two hydraulic rods are fixedly installed on the frame and electrically connected to an external controller. The external controller is used to control the two hydraulic rods to work synchronously. A sleeve is fixedly installed on the base, and an inner groove is formed on both sides of the sleeve. A vertical rod is inserted into the sleeve, and two sliders are fixedly installed on the vertical rod. The sliders are slidably disposed in the inner grooves. The upper end of the vertical rod is fixedly installed on the lower template.

[0013] Preferably, two symmetrically distributed elastic elements are provided between the movable seat and the upper mold. The two ends of the elastic elements are fixedly connected to the movable seat and the upper mold, respectively. A first spring is fixedly connected to both sides of the sleeve, and the end of the first spring is fixedly connected to the strip seat.

[0014] Preferably, a servo motor is fixedly mounted on the base, and an eccentric wheel is fixedly mounted on the output shaft end of the servo motor.

[0015] Preferably, a second spring is provided inside the sleeve, with its upper and lower ends fixedly connected to the vertical rod and the sleeve, respectively. An annular plate is fitted and fixedly connected to the upper end of the sleeve, and a third spring is fitted outside the vertical rod, with its upper and lower ends fixedly connected to the annular plate and the lower template, respectively.

[0016] Preferably, it further includes an upward moving mechanism, which is mounted on two strip seats and is connected to the lower template and used to move the lower template upward.

[0017] Preferably, the upward moving mechanism includes a rack, which is fixedly connected to the lower template. Side plates are fixedly installed on each of the strip seats. A rotating shaft is rotatably installed between the two side plates. An incomplete gear is fixedly installed on the rotating shaft and meshes with the rack. A stepper motor is fixedly installed on one side of the strip seat, and a synchronous belt mechanism is installed between the output shaft of the stepper motor and the rotating shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] By using hydraulic rods to pull the vertical rod and lower mold plate downwards, the lower mold plate separates from the upper mold. This device assists in detaching the blocks from the mold cavity, eliminating the need for manual separation. The demolding action is seamless, significantly reducing demolding time. Automated demolding reduces manual operation, decreases reliance on skilled workers, and saves labor costs. Improved demolding efficiency allows for the production of more blocks per unit time, increasing overall production capacity.

[0020] During the injection process, the centrifugal force of the eccentric wheel generates a controllable lateral impact force, causing the upper and lower molds to vibrate horizontally. This causes the sludge-based material within the mold cavity to flow, effectively expelling air and preventing structural defects caused by residual air bubbles. Vibration also breaks up stratification caused by differences in material flowability or density, ensuring uniform mixing of all components within the mold cavity and improving the overall strength and stability of the blocks.

[0021] The incomplete gear rotates and intermittently drives the rack upward, stretching the second and third springs. When the incomplete gear separates from the rack, the elastic force of the second and third springs causes the lower template and the blocks on it to move downward quickly. The blocks on the lower template separate from the lower template under inertia, eliminating the need for manual removal of the block molded parts from the lower template and avoiding damage to the block molded parts by the workers.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figure 1-9 A high-strength, lightweight silt-based ecological slope protection block pressing and molding equipment includes a frame 1, an upper mold 2 inside the frame 1, and connecting mechanisms at both ends of the upper mold 2. The upper mold 2 is mounted on the frame 1 via the connecting mechanisms. The lower end of the upper mold 2 is open, and a lower template 3 is provided at the bottom port of the upper mold 2, forming a mold cavity between the lower template 3 and the upper mold 2. A demolding mechanism is provided on the frame 1, which is connected to the lower template 3 and assists in separating the lower template 3 from the upper mold 2. The inner wall of the upper mold 2 is coated with Teflon, and an injection mechanism is provided on the upper mold 2, which is connected to the mold cavity and used to add raw materials into the mold cavity.

[0035] After applying a Teflon coating to the inner wall of the upper mold 2, the Teflon coating has an extremely low coefficient of friction, which significantly reduces the friction between the block product and the upper mold 2, making it easier for the block product to be removed from the upper mold 2. The Teflon coating has extremely low surface energy, making it difficult for the product to adhere to the upper mold 2, further reducing the difficulty of demolding. However, the connection force between the lower mold 3 and the block product is relatively large.

[0036] The injection mechanism includes a feed pipe 4. The lower end of the feed pipe 4 is fixedly installed on the upper mold 2 and communicates with the mold cavity. The upper end of the feed pipe 4 is provided with two pipe openings, one of which is set vertically and the other is set at an angle.

[0037] A block 5 is fixedly installed inside the feed pipe 4. A pusher 6 is slidably arranged inside the feed pipe 4. An exhaust port is provided on the pusher 6. A screw 7 is rotatably installed on the pusher 6. The upper end of the screw 7 passes through the block 5 and is threadedly connected to the block 5. A handle is fixedly installed on the upper end of the screw 7.

[0038] The connecting mechanism includes a slide rail 8 on the frame 1, a movable seat 9 is slidably arranged in the slide rail 8, a connecting block 11 is inserted into one end of the movable seat 9, the connecting block 11 can move horizontally, and one end of the connecting block 11 is fixedly installed on the upper mold 2. Two spaced limiting holes 12 are opened on the frame 1, and a limiting rod 13 is provided on the frame 1. The limiting rod 13 passes through the limiting holes 12 and is inserted into the movable seat 9.

[0039] During injection molding, the limiting rod 13 passes through the limiting hole 12 below and is inserted into the movable seat 9, which can limit the movable seat 9, the connecting block 11 and the upper mold 2. Then, the processed raw material is added through the inclined port of the feed pipe 4, and the raw material is introduced into the mold cavity between the upper mold 2 and the lower mold plate 3 through the feed pipe 4.

[0040] The demolding mechanism includes two symmetrically distributed strip seats 16, which are located inside the frame 1 and below the lower template 3. Each strip seat 16 has a slot 14, which are symmetrically distributed. A base 15 is provided inside the frame 1, with both ends of the base 15 inserted into the slots 14 on both sides. The base 15 can slide within the slots 14. Two hydraulic rods 17 are fixedly installed on the frame 1, and the two hydraulic rods 17 are electrically connected to an external controller. The external controller is used to control the two hydraulic rods 17 to work synchronously. A sleeve 18 is fixedly installed on the base 15, with inner grooves 19 on both sides of the sleeve 18. A vertical rod 20 is inserted into the sleeve 18, and two sliders 10 are fixedly installed on the vertical rod 20. The sliders 10 are slidably disposed in the inner grooves 19. The upper end of the vertical rod 20 is fixedly installed on the lower template 3.

[0041] After the raw material has solidified, the hydraulic rods 17 on both sides work synchronously and output the same distance. The hydraulic rods 17 drive the strip seat 16 to move down, and the base 15 and sleeve 18 move down synchronously. This can pull the vertical rod 20 and the lower template 3 down, so that the lower template 3 separates from the upper mold 2. The block forming part has a small adhesion force to the upper mold 2 and separates, while the block forming part has a large adhesion force to the lower template 3 and stays together. The block forming part can then be manually removed from the lower template 3.

[0042] The device assists in detaching blocks from the mold cavity without manual separation. Hydraulic rods drive the strip seat, base, and sleeve to move downwards in tandem, causing the vertical rod and lower mold plate to detach from the upper mold as a whole. The action is seamless, significantly reducing demolding time. Automated demolding reduces manual operation, decreases reliance on skilled workers, and saves labor costs. Improved demolding efficiency allows for the production of more blocks per unit time, increasing overall production capacity.

[0043] When there is adhesion between the upper mold 2 and the block, the screw 7 is rotated to drive the push block 6 to move downward along the feed pipe 4. The push block 6 moves into the upper mold 2 and presses down on the block in the mold cavity, thereby pushing the block out of the mold cavity.

[0044] Two symmetrically distributed elastic elements 21 are provided between the movable seat 9 and the upper mold 2. The two ends of the elastic elements 21 are fixedly connected to the movable seat 9 and the upper mold 2, respectively. A first spring 22 is fixedly connected to both sides of the sleeve 18, and the end of the first spring 22 is fixedly connected to the strip seat 16. A servo motor 23 is fixedly installed on the base 15, and an eccentric wheel 24 is fixedly installed on the output shaft end of the servo motor 23.

[0045] After the injection is completed, in order to avoid uneven distribution of raw materials in the mold cavity, the eccentric wheel 24 is rotated by the servo motor 23, which can cause the base 15 to vibrate in the horizontal direction. The base 15 slides in the slot 14, and the connecting block 11 slides in the movable seat 9, which can drive the upper mold 2 and the lower mold plate 3 to vibrate in the horizontal direction.

[0046] Horizontal vibration generates a controllable lateral impact force through the centrifugal force of the eccentric wheel 24, causing the sludge-based raw material within the mold cavity to flow, effectively expelling air and preventing structural defects caused by residual air bubbles. Vibration breaks up the stratification phenomenon caused by differences in flowability or density of the raw material, ensuring that all components are uniformly mixed within the mold cavity, thus improving the overall strength and stability of the block. During vibration, the raw material particles rearrange in the horizontal direction, reducing the gaps between particles and significantly increasing the density of the raw material within the mold cavity, resulting in a denser block with improved compressive strength and durability.

[0047] Based on Example 1, Example 2:

[0048] In Example 1, pulling the vertical rod 20 and the lower template 3 downwards separates the lower template 3 from the upper mold 2. The block forming part has weak adhesion to the upper mold 2 and separates, while the block forming part has strong adhesion to the lower template 3 and remains connected. Subsequently, the block forming part can be manually removed from the lower template 3. However, when manually removing the block forming part from the lower template 3, the force applied by the worker's hands may damage the block forming part.

[0049] Reference Figure 2-9 The sleeve 18 contains a second spring 25, whose upper and lower ends are fixedly connected to the vertical rod 20 and the sleeve 18, respectively. An annular plate 26 is fitted and fixedly connected to the upper end of the sleeve 18. A third spring 27 is fitted over the vertical rod 20, with its upper and lower ends fixedly connected to the annular plate 26 and the lower template 3, respectively. An upward-moving mechanism is also included, mounted on two strip seats 16. This mechanism is connected to the lower template 3 and used to move the lower template 3 upwards. The upward-moving mechanism includes a rack 28, which is fixedly connected to the lower template 3. Side plates 29 are fixedly mounted on each strip seat 16. A rotating shaft 30 is rotatably mounted between the two side plates 29. An incomplete gear 31 is fixedly mounted on the rotating shaft 30, meshing with the rack 28. A stepper motor 32 is fixedly mounted on one side of the strip seat 16, and a synchronous belt mechanism 33 is installed between the output shaft of the stepper motor 32 and the rotating shaft 30.

[0050] After the block forming part and the lower template 3 move down, remove the limiting rods 13 on both sides, and then move the upper mold 2 up to insert the limiting rods 13 into the upper limiting holes 12 to fix the upper mold 2. Then start the stepper motor 32, which drives the rotating shaft 30 to rotate through the synchronous belt mechanism 33. The incomplete gear 31 on the rotating shaft 30 rotates and intermittently drives the rack 28 to move up. The second spring 25 and the third spring 27 are stretched. When the incomplete gear 31 separates from the rack 28, the elastic force of the second spring 25 and the third spring 27 drives the lower template 3 and the block on it to move down quickly. The block on the lower template 3 separates from the lower template 3 under the action of inertia. If the two do not separate, repeat the process multiple times. This eliminates the need to manually remove the block forming part from the lower template 3 and avoids damage to the block forming part by the workers.

[0051] General working principle:

[0052] During injection molding, the limiting rod 13 passes through the limiting hole 12 below and is inserted into the movable seat 9, which can limit the movable seat 9, the connecting block 11 and the upper mold 2. Then, the processed raw material is added through the inclined port of the feed pipe 4, and the raw material is introduced into the mold cavity between the upper mold 2 and the lower mold plate 3 through the feed pipe 4.

[0053] After the injection is completed, in order to avoid uneven distribution of raw materials in the mold cavity, the eccentric wheel 24 is rotated by the servo motor 23, which can cause the base 15 to vibrate in the horizontal direction. The base 15 slides in the slot 14, and the connecting block 11 slides in the movable seat 9, which can drive the upper mold 2 and the lower mold plate 3 to vibrate in the horizontal direction.

[0054] After the raw material has solidified, the hydraulic rods 17 on both sides work synchronously and output the same distance. The hydraulic rods 17 drive the strip seat 16 to move down, and the base 15 and sleeve 18 move down synchronously. This pulls the vertical rod 20 and the lower template 3 down, causing the lower template 3 to separate from the upper mold 2. The block forming part has a small adhesion to the upper mold 2 and separates, while the block forming part has a large adhesion to the lower template 3 and remains connected. After the block forming part and the lower template 3 have moved down, the limiting rods 13 on both sides are removed. Then, by moving the upper mold 2 up, the limiting rods 13 are inserted into the upper limiting hole 12 to fix the upper mold 2. Restart the stepper motor 32, which drives the rotating shaft 30 to rotate via the synchronous belt mechanism 33. The incomplete gear 31 on the rotating shaft 30 rotates and intermittently drives the rack 28 to move upward. The second spring 25 and the third spring 27 are stretched. When the incomplete gear 31 separates from the rack 28, the elastic force of the second spring 25 and the third spring 27 drives the lower template 3 and the blocks on it to move downward quickly. The blocks on the lower template 3 separate from the lower template 3 under the action of inertia. If the two do not separate, repeat the process multiple times.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
